1. A blood removal system, including:

  • a housing;

    a lancet drive connected to the housing including a spring, a cocking element, a rotatable rotor and a coupling mechanism, the cocking element being connected to one end of the spring and configured to rotate in a first direction in a cocking movement thereby tensioning the spring when rotor rotation is inhibited, and to resist rotation in a direction opposite the first direction during a drive phase of the lancet drive wherein rotor rotation is permitted and converted by the coupling mechanism into movement of a lancet in a puncturing direction such that a tip of the lancet exits an opening of the housing to produce a wound.
